Knox was tasked by General Washington in the American Revolution with transporting cannons from Fort Ticonderoga. He moved the cannons via ox-drawn sleds over 300 miles of winter terrain until they arrived at Dorchester Heights forcing the British arm to evacuate. Knox was also responsible for managing the logistics of General Washington’s famous crossing of the Delaware River and managed the siege of Yorktown. After the Revolution, Knox served as the first secretary of war for the United States.
